Automotive engines are getting smaller with tighter manufacturing tolerances. As a result, cleanliness standards are becoming more rigorous and cleanliness inspections have become a requirement rather than a luxury. CleanCHK is a fully-integrated solution that combines a scanning electron microscope (SEM) for high-resolution imaging and an X-ray spectrometer to determine elemental composition. With the CleanCHK analyzer, we can detect and count particles as small as 0.5 microns, characterize their size and shape, and perhaps most importantly, determine their composition. (details)
